ABSTRACT:
This invention relates to a method for producing a composite container having a body label or tubular sleeve mounted thereon adapted to be shrunken onto exterior surface areas of a cylindrical container. The tubular sleeve is preformed of thin flexible thermoplastic material and may be flat-folded until ready for use when it is fully opened and conveyed in axial registry with the container inverted therebeneath. The sleeve preform of heat-shrinkable plastic material is telescopically assembled onto the inverted container while the latter is conveyed through a coincidental aligned path. The container preferably consists of a hollow glass or plastic container held invertedly by its neck portion with the tubular preform made slightly larger in diameter to surround the body and neck portions of the container. The tubular sleeve preform is held fully opened and is then transported downwardly in telescopic relation when in axial alignment with the inverted container. The opened sleeve and upright inverted container are continuously moved in synchronism in a coincidental lineal path for such sleeve mounting in temporary relation on the container body and neck where it is adapted to controlled heat-shrinking in place in permanent conforming arrangement.
